Objectives: To realize the dynamic visualization of forensic odontology based on the bibliometrics methods, and capture the research hotspots and identify the future development trend.
Methods: Literature articles published from January 1995 to December 2020 were searched according to specific subject words in the core data set of Web of Science. The visualization analysis of publishing country, institution, discipline, author, co-cited journal and keywords was performed by CiteSpace 5.7.R5W software.
Results: The annual analysis of publications showed an upward trend of forensic odontology research literature year by year, with the number of annual publications more than 110 in the last five years. Developed countries were the main source of contributions and the average centrality was greater than 0.2. The research of forensic odontology involved multiple disciplines, including stomatology, biology, computer science and medical imaging, with a distinct interdisciplinary feature. A total of 115 nodes were obtained by keyword cluster analysis. The principal line of forensic odontology mainly included individual identification and age estimation and the emergence of hotspots was closely related to new technologies. Population-based odontology investigation, improvement of traditional dental age estimation method and dental age estimation based on new technology were popular research in forensic odontology.
Conclusions: Developing countries urgently need to increase the focus on related research. It may be an important direction for the development of forensic odontology to establish and enrich the regional dental database, develop new odontology identification technology combined with frontier and high-end technology, and develop the identification program based on advanced information technology.

Children are particularly vulnerable to fatalities from fire incidents, and the crucial role of dentition in the identification processes is well known. Despite this, research on burned deciduous teeth is lacking, often assuming similarities with burned permanent teeth, disregarding their morphological and chemical distinctions. This goal of this study was to investigate the effect of burning on deciduous teeth, focusing on post-burning tooth color assessment.

Introduction: In the forensic field, having accurate understanding of the macroscopic and microscopic alterations that occur in teeth when exposed to temperatures has remarkable significance. The preservation of delicate incinerated teeth is crucial in fire investigations that pertain to the temperature exposed, as well as the identification of victims. This preservation is necessary in order to conduct macroscopic and microscopic ultra-structural examinations, which provide valuable insights into the structural alterations that dental tissues undergo when exposed to low to high temperatures.

Article Synopsis
- Estimating human chronological age is crucial in forensic science, and this study compares skeletal maturation and dental mineralization methods for accuracy in Egyptian children and adolescents.
- The research included 176 participants aged 8-16, analyzing radiographs with the Fishman and Nolla methods, revealing that both are valid age predictors but Nolla outperformed Fishman.
- Nolla slightly underestimated age while Fishman overestimated it, and the study recommends using only the Nolla method for age estimation, as it provides the most reliable results without needing additional radiographic assessments.
Palatal rugae assessment using plaster model and dental scan: a cross-sectional comparative analysis.
Front Oral Health

Dental School, University of Bari, Bari, Italy.
Objective: Due to their consistent and individualistic patterns, palatal rugae (PR) are used in forensic dentistry as an ancillary method for personal identification. This study aimed to compare the impression of the PR obtained with the classic alginate impression and casting of the plaster model with the impression of the palate made with an intraoral scanner. Both impressions were compared with each other and with the photograph of the palatal rugae.
